W7005630 - Replacement Control Knob 1/4" ID x 1.25" OD

Technical Overview

The W7005630 is a specialized replacement control knob designed for industrial welding power sources and wire feeders. Engineered to precise dimensional standards, this component features a 1/4-inch (0.250") inner diameter, making it compatible with standard potentiometer shafts used in voltage, amperage, and wire feed speed controls. The knob's outer diameter measures 1.25 inches, providing sufficient torque leverage for fine adjustments, while the 0.9-inch height ensures a compact profile that minimizes the risk of impact damage in active work zones.

Manufactured from high-density, impact-resistant polymer, the W7005630 is built to withstand the thermal and mechanical stresses typical of heavy fabrication environments. The material offers excellent resistance to oils, solvents, and UV exposure, ensuring longevity and consistent performance. The internal bore is machined to ensure a secure fit on the control shaft, preventing slippage during operation. This part serves as a direct replacement for damaged or missing knobs on compatible Lincoln Electric equipment, restoring full interface functionality to the operator.
